Interestingly, I can project using ToArray or ToList extension methods, but it is inefficient to pull a whole record set in through Hql only to turn around and filter some instances afterwards. If I can work through the Linq provider as the Hql is being generated, that would be best, I think. > Thoughts? > > >> воскресенье, 6 марта 2016 г., 23:46:34 UTC+3 пользователь mwpowellhtx >> написал: >>> >>> Hello, >>> >>> I've got a semi-rich domain model that supports some methods.
